Column Compartment
The column compartment can be used in its standard version for 4.6 mm
inner diameter columns. At flow rates above 2 mL/min, and temperatures
above 60 °C, the column effluent should be cooled down to the
temperature of the detector by using the 1.5 µL cooler/heater in the
column compartment. This ensures lowest noise level with UV detectors,
even at 5 mL/min and 80 °C (see Figure 18 on page 56 ).

If 2.1 mm inner diameter columns are used at low flow rates, the small
heating device should be used for lowest extra- column volume.
